ExploraTour - How to Build a Star

To understand how things work sometimes you have to take them apart and
look inside. We can't really look inside of a star but we can try to
imagine what it might be like. Let's start with looking for the source of
a star's power.

A lot of things in your house need power to run. Your remote control cars
need batteries. Your radio needs to be plugged into the wall because it
runs on electricity. Stars are very different from anything you've seen on
Earth. Stars work by changing matter into energy. That's right ... the stuff
that makes up all of the things on Earth is changed into energy (heat and light)
inside of a star!

It just takes a little matter to make a whole lot
of energy. Look at the jellybean in the picture. If all the matter in that
jellybean were changed into energy there would be a very big explosion -- big
enough to blow up a small island.
